Tianwen-2 Target Asteroid (469219) Kamo’oalewa Probably Develops An Itokawa-compositional But Ultra-highly Space-weathered Surface
China’s Tianwen-2 mission plans to return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo’oalewa. Previous studies linked Kamo’oalewa to lunar composition and origin.
